Description 4-20mA RS485 Split plug in Thermo Hygrometer humidity and temperature transducer
The sensor adopts high precision temperature humidity integrated
chip. The temperature is measured by using diode temperature sensing p-n junction, and the forward step-down chSplit plug in temperature and humidity transmitter with RS485anges with temperature under constant current. Humidity is measured by humidity sensitive capacitance, which changes with the change of humidity. The temperature and humidity are compensated for each other, and then amplified into standard digital or analog signals of relative humidity and temperature through amplification circuit.Temperature and humidity transmitter cws21 is applicable to the measurement of temperature and humidity in pipes or boxes.(this protocol complies with Modbus communication protocol and adopts the subset of Modbus protocol RTU mode. RS485 half duplex working mode)
A) output signal: RS485 (distance can reach 1000m). 32 in total)
B) standard Modbus RTU protocol
(03 function reads data, 06 function writes setting data)
C) data format: 9600, N, 8,1 (9600bps, no verification, 8-bit data, 1-bit stop) D) output data: temperature 0-1650 (- 40-125 ℃)
Humidity 0-1000 (0-100% RH)
E) response frequency: ≤ 2Hz
